refactor: migrate Element_ae_crud v1/v2 usages to element_ae_obj_field_editor_v3

Replace all active Element_ae_crud (v1) and Element_ae_crud_v2 usages across
22 files with Element_ae_obj_field_editor_v3. Also remove 9 commented-out v1
imports that were dead code.

Key changes:
- Remove trigger_patch pattern; replace with direct api.update_ae_obj_v3() calls
- Replace field_value prop with current_value, on:ae_crud_updated with on_success
- Remove legacy props: api_cfg, hide_edit_btn, outline_element, show_crud,
  display_inline, display_block_edit (→ display_block), class_li
- field_type 'boolean' → 'checkbox', 'email' → 'text' (v3 has no email type)
- Replace core_func.update_ae_obj_id_crud_v2() with api.update_ae_obj_v3()
- Keep core_func where still used (QR code generation, person create)

Files: presenter_view, person_view, location_view, device_obj_li,
presentation_obj_li, session_view, launcher_file_cont, session_alert,
event/session/location/presenter page menus, leads exhibit tracking page
